Speed prior to falling off rotarod
- Scales for body weight
- Accelerating rotarod (spindle diameter 30 mm and lane dimension of 50 mm; 20 rpm/min)
Procedure: Accelerating rotarod
- All testing is conducted during the animal's light cycle.
- Mice are weighed on test day.
- Mice are placed on a rotarod spindle at a 45-degree angle.
- Mice are subjected to a slow-speed waiting mode (4 rpm for 5-10 s).
- Acceleration is started after the waiting period and set for 20 rpm/min for all mice.
- Animal falls are detected by a pressure sensitive lever, which automatically stops and records the speed at the time of the fall.
- Mice are tested consecutively an average of 3.3 times (range: 3-5).
- Repeat measurements of speed at the time of animal falling are averaged.
